ratenteaiuayr, 1912. Serial N0. 609,716.

To all whom it may concern:

Be it known that I, ERNEST W. MORGAN, a citizen of the United States,residing at Oakland, in the county of Alameda, State of California, haveinvented certain new and useful Improvements in Envelope; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to envelops.

The object of the invention resides in the provision of an envelop whichis so constructed that the surreptitious removal of the contents can beeasily and positively detected.

With this object in view, the invention consists in the details ofconstruction and combination of parts to be hereinafter more fullydescribed and particularly pointed out in the appended claim.

In describing the invention in detail, reference will be had to theaccompanying drawing lwherein like characters of reference denotecorresponding parts in the views; and in which,

Figure 1 represents an envelop blank looking at the inner face of thefront and constructed in accordance with the invention; Fig. 2, a frontview of the envelop showing the effect produced upon same by the removalof its contents; and Fig. 3, a transverse section through an envelopconstructed in accordance with the invention, said .envelop beingprovided with contents which are secured to the detachable section ofthe front of the envelop.

Referring to the drawing, 10 indicates the front of the envelop; 11 and12, the side flaps; 13, the bottom flap; and 14C, the closure. A portionof the front 10 is shown as dened by the perforations 15 so as toproduce a weakened line and the portion so dened has its inner faceprovided with a coating` of adhesive material 16.

In use, the adhesive material 16 is moistened before the contents of theenvelop are placed therein so that said contents will be positivelysecured to the portion of the front 10 which is defined by theperforations 15. When this status exists in the envelop, it will beapparent that should the envelop be surreptitiously opened and thecontents removed, the connection between the contents and the portion ofthe front defined by the perforations 15 will be torn out and indicatesuch surreptitious opening and removal of the contents.

What is claimed is An envelop having its front providedV ERNEST W.MORGAN.
